Unbelievable!! The sequence starting at
1:56 shows three cub scouts. The one on the far right is me! I nearly fell off my chair. Pleased to note that I'm still kicking, 76 years old, and retired in Las Vegas, NV. Sorry to add that the Monnier School still stands but it has been closed for nearly a decade. No, I don't remember someone making movies then! By the way, the cars all have 1948 Michigan license plates on them, not 1947, so I guess that corrects the date.
